Electrical and seismic responses of shallow, volcanogenic, massive sulphide ore deposits
… content of volcanogenic sulphide ores. SP, soil geochemistry and electrogeochemistry are found to be the most effective exploration methods followed by resistivity/IP and seismic refraction. The large SP responses over both ore zones are simulated using new methods which allowed the width …

Trace element abundance and human epidemiology in Northern Ireland: the Tellus case study
… trace elements (eg. As, Ni, Pb, Cr, Cdand U) in soil and water as well as subsequent residual concentrations within thefood chain, together with the presence of relevant human exposure pathways, mayexplain the spatial variability of certain disease patterns. It has been recognizedthat besides …

The First Insights into the Phylogeny, Genomics, and Ecology of the Novel Bacterial Phylum Armatimonadetes
… sites rather than with other factors, such as soil geochemistry or microbial communities of the sites. The correlation between geography and phylogeny, low abundance of C. calidirosea at all sample sites (ranging from 0.006 % to 0.3 %), and the high genomic conservation indicated rapid aeolian …

Miocene paleoenvironments and paleosol pH proxies.
… that draws on sedimentology, stratigraphy, geochemistry, and geostatistics. This dissertation includes two paleoenvironmental case studies and the development of a new suite of proxies for soil pH. The first case study was performed at Coffee Ranch, the site of a late Miocene (6.6 Ma) …
